Full liquid screw water-cooled chiller unitfunction
Fully equipped with security protection functions
Pressure protection: automatic protection devices for high and low pressure in refrigeration systems;
Power protection: undervoltage protection, phase loss protection, reverse phase protection, overload protection, motor overheating protection;
Anti freezing protection: When the temperature of the chilled water is too low, the unit will automatically shut down;
Safety valve protection: When the refrigerant pressure exceeds a certain value, the safety exhaust valve will automatically open;
Delay protection: Compressor delay start protection to prevent frequent compressor starts;
Oil level protection: activate the protection device when the oil level of the compressor is too low;
Water flow protection: When the water flow stops or decreases, continuing to operate will harm the unit and the unit will automatically shut down;

Full liquid screw chiller unitspecifications

kasselFull liquid screw chiller unitThe use of a full liquid evaporator has higher heat transfer efficiency, with the outlet water and evaporation temperature approaching each other. It has the characteristics of small temperature difference and low resistance along the way, making it suitable for units with large circulation volume. The refrigeration effect is very strong, and it can be combined with end treatment equipment to form a large centralized air conditioning system with a wide range of applications. The unit has a compact structure, small footprint, simple pipeline design, only requires external water pipes, and is easy to install and maintain. Therefore, it has the advantages of high efficiency, energy saving, green environmental protection, reliability, durability, and low vibration and noiseFull liquid screw chiller unitGood product quality and after-sales service have won applause from customers, with numerous successful cases of customer applications, and improved the reputation of the enterprise.

characteristic
The semi enclosed screw compressor used ensures long-term safe and stable operation of the unit, with a long service life;
2. Adopting an efficient full liquid evaporator greatly increases the COP value compared to traditional dry evaporators, saving 15-25% in operating costs
3. The unit adopts PLC control to achieve "one click startup" and fully automatic operation; The unit control system can be equipped with a built-in web browser, and users can remotely monitor the operation status and query the working parameters of the unit from any computer through the Internet network
4. According to user needs, the heating recovery function can be added. In summer, the heat recovery capacity can reach 30% -40% of the cooling capacity, and in winter, the maximum heat recovery capacity can reach 75%. While meeting the cooling needs, the heat source side can also be improved
5. Partially or completely recycling and utilizing the discarded heat greatly reduces the operating costs of the unit:
6. The design of the outer fins of the heat exchange tube enhances the vaporization core required for nucleate boiling, thereby improving the heat transfer efficiency outside the tube; The design of the inner ridge of the heat exchange tube increases the heat transfer area and improves the heat transfer efficiency inside the tube. Increasing disturbance turns laminar flow into turbulent flow and delays scaling:
7. Electronic expansion valves can more accurately regulate refrigerant flow and control evaporator liquid level;
8. Efficient secondary oil separation and reliable injection pump oil return system have solved the oil return problem of full liquid units, ensuring that the compressor runs for a long time without losing oil and making the unit operate stably and reliably;
9. Automatic power on/off, automatically achieving unmanned operation management according to the predetermined work plan
10. Multiple password settings ensure that the device will not be shut down or damaged due to accidental factors
